Abstract
The present invention provides a kind of preparation method of composite material for nanometer injection molding, in turn includes the following steps：Direct current of two step pre-etching of mechanical pretreatment, which is powered, corrodes secondary dipulse energization corrosion post-treatment drying nano injection, and corrode in galvanization with ultrasonic wave added, the base material of composite material is one kind in aluminium alloy, titanium alloy, magnesium alloy or stainless steel, which can be applied to the preparation of mobile communication terminal shell.
Description
Technical field
The present invention relates to field of metal surface treatment, more particularly, to one kind using stainless steel, titanium alloy, aluminium alloy as base material
Preparation method and application for the composite material of nanometer injection molding.
Background technology
Japanese great achievement plastics（Taiseiplas）Nanometer forming technique was invented in 2002 by Co., Ltd.（NMT）, the skill
Art is by metal and the integrated nanometer forming technique of plastics, can be widely used in metal and resin integrated molding thin light, just
On the shell for the mobile electronic product taken, such as computer terminal, cell phone.
Now in the art, the treatment process of NMT includes flow as follows：The metal for needing to combine is carried out at lye
Reason, acid treatment, weak acid treatment, wash with water again it is clean after be dried, be molded.Nothing will be formed after processing in metal surface
The micropore that several apertures is about 20nm, that is to say, that may be considered and formd on metal surface after treatment very much
Small concaveconvex structure, the resin of injection enter in these concaveconvex structures, produce anchoring effect, in other words：Metal base is first
The impurity such as the grease on surface are removed by alkali cleaning, the metal oxide on surface is removed by pickling and etches nanoscale hole hole；
Smaller nanoscale hole hole is etched by T processing again；Metal after washing and drying is clamped in mould, and plastics note
Modeling reaches integral structure, is drawn by above-mentioned record, the key technology of NMT be processing for base material and nano injection into
The operation of type, and the metal oxide on surface is removed by pickling and etches nanometer or big face often occurs in micron order hole
Product excessive erosion, can not only form effective duct, can occur plane dissolved corrosion on the contrary, heavy losses substrate metal, in addition,
The duct that acid corrosion is formed is concentrated mainly on nanoscale, since duct is too small, is unfavorable for the flowing injection of resin, and easily formed
Gas barrier, is unfavorable for contact of the resin with base material, therefore the nanometer injection of metal base faces following problem at present：（1）Base
Material etch pit is small, and duct depth as shallow, cannot effectively be penetrated through between duct；（2）Since duct forms poor, it is unfavorable for resin
Attachment, and cause the combination power of resin and base material weaker, the combination force difference opposite sex between resin and base material is larger, with reference to uniformity
It is poor.
The content of the invention
Based on the above problem, the present invention provides a kind of preparation method of composite material for nanometer injection molding and answers
With, prepare nanometer injection molding composite material the step of it is as follows：- direct current energization corrosion of the step of mechanical pretreatment-two pre-etching-
